Specification of Letters Patent.

Application filed March 22, 1912. Serial No. 685,401.

To all "Lo/mmit may concern Be it known that T, ARTHUR D. MAR- co'r'rn, a citizen of the United States, and a resident of Eunice, in the parish of St. Landry and State of Louisiana, have made certain new and useful Improvements in Oil-Burners, of which the following is a specification.

My invention relates to improvements in oil burners, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a device for burning heavy or low grade oil, such as crude oil, so as to effect a complete combustion thereof, and obviating the annoyance of smoke which often accompanies the burning of oils of this character.

A further object of my invention is to provide a device in which the vapors of water and oil are mixed, the water being carried in a convenient portion of the burner and being delivered in the form of steam and mixed with the oil, these two constituents afterward being mixed with air for facilitating the combustion.

A further object of my invention is to provide an efiicient burner for heavy oils which is of comparatively simple construction, and which is therefore cheap to manufacture.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in accompanying drawings forming part of this application in which Figure 1 is a side view of the burner, Fig. 2 is a plan view thereof, Fig. 3 is a section along the line 33 of Fig. 4, and Fig. 4 is a section along the line 44 of F 1.

In carrying out my invention I provide a pipe 1 leading to an oil supply (not shown) and a pipe 2 leading to a water supply (not shown) these pipes being provided with valves 3 and 4 respectively. Connected with the valve 3 is a U-shaped tube 5 which extends laterally from the pipe 1 and has a return portion, as shown in Figs. 1 and 2. The pipe 2 communicates with a tube 6, which, as shown in Fig. l, is inclined in a downward direction, and is provided with an end cap 7, which closes the tube. The tube 6 is in communication with a pipe 8, as will be seen from Fig. 2, the U-shaped tube 5 being also in communication with the pipe S. It will be noted that the connection 6* between the tube 6 and the pipe 8 straddles the pipe 5. This is for the purpose of elevating the upper end of the water generator. The end of the tube 8 projects into the open end of a pipe 9 disposed directly above the outer casing 10 of the burner proper. This pipe 9 is connected by means of an elbow 11 with an inner tube 12. The latter is threaded at one end to receive a cap 13.

In order to secure the outer casing 10 in place, I provide the tube 12 with a pair of tapering plugs or washers l3 and 14 re spectively. The former is carried by the tube 12 at one end thereof and the latter is forced into the end of the casing 10 by means of the cap 13'" so that the casing 10 is held securely in position between these two plugs 13 and 14, as clearly shown in Fig. 3. The inner tube 12 has four rows of perforations 12 these rows being at right angles, as will be seen from Fig. 4. The outer tube or casing 10 is also provided with perforations for the escape of the gas.

From the foregoing description of the various parts of the device the operation thereof may be readily understood.

The burner as a whole is designed to be inserted in the combustion chamber C indicated in dotted lines in Figs. 1 and 2. The pipes l and 2, the valves 3 and 4, and the open. end of the pipe 9, it will be observed, are without the combustion chamber 6. The valve 3 is open to permit a flow of oil from the pipe 1 through the U-shaped portion 5, which is above the burner proper. The valve 4 is also open to permit a flow of water into the pipe 6. This pipe 6 being within the combustion chamber C is heated and the steam from the water passes around to the pipe 8 where it meets the vaporized oil and carries it into the tube 9. The movement of the oil and water entrains a quantity of air which enters at the open end of the pipe 9, as shown in Fig. 3. This mixture of air, water vapor and oil vapor is then passed directly above the hottest part of the burner and is delivered into the pipe 12, from which it issues. It then passes through the openings in the outer casing 13 and being ignited burns with a fierce heat.

In practical experiments I have found that this burner is free from smoke and burns evenly With a very hot flame. It Will vaporize heavy oils Whichnecessitate a high temperature before their free volatilization. The casing 10 forms a shield for the pipeor tube 12. In case this casing should burn out it can be very readily removed and another one replaced by unscrewing the cap 13, and

pulling the casing 10 and the Washer or plug 14 oil? from the pipe 12 When another casing may be substituted.

The-burner is especially desirable for use in cooking or heating stoves that Were builtoriginally to use Wood or coal, since it is compact and takes up small space in the fire box.

The liability of an explosion is reduced to a minimum as the place of mixture of the oil, Water vapor and gas is outside of the combustion chamber.

The use-of a burner of this kind is very eflicient, since the oil is thoroughly heated, and in a completely vaporized state before being burned; Furthermore the projection of the steam and oil forward with a free access of air insures a thorough commingling of the combustibleconstituents.

1. In an oil burning device, a central perforated tube, an exterior removable perfo rated casing carried'by said central tube, a pipe disposed above said outer casing and having communication With the interior of said central tube, one end of said pipe being open, means fordelivering a mixture of oil vapor and air into said open end, said means comprising an oil supply pipe and a Water supply pipe, a U-shaped tube disposed above said perforated casing and connected With said oil supply pipe, a Water receptacle disposed adjacent to the exterior of said casing and connected to said Water supply pipe, and a common conduit communicating With said water receptacle and With said U-shaped tube and arranged to extend into the open end of said first mentioned pipe.

2. In an oil burning device, a central perforated tube, an exterior removable perforated casing'carried by said central tube, a pipe disposed above said outer casing and having communication With the interior of r ARTHUR D. MARCOTTE.
